feat(templates): visual graph builder

Canvas mode in the template editor (lazy-loaded React Flow): service
nodes for web/worker/cron/database, connect handles to set depends_on,
per-node inspector (image/repo, engine, port, health check, env,
volumes), live validation (dup keys, missing deps, cycles, missing
source), and an Apply step that serializes back to the version-2 graph
config JSON.

- builder-model.ts is pure: config↔canvas round-trip, layered
  auto-layout, flat-legacy→single-node migration, validation —
  16 vitest cases cover all of it
- node positions persist under config.canvas (backend ignores unknown
  config keys, so no schema change)
- flat legacy templates open as a single node so nothing is lost on
  edit

-  UI flow: one SSH session runs agent install (binary + systemd +
-  enroll token), SSH closed forever. dflow onboarding UX, agent-model
-  security.
-- [ ] **Mesh awareness** — agent detects + reports tailscale0/netbird0/
-  zt0 IPs at register; backend stores + displays. Optional
-  `TAILSCALE_AUTH_KEY` enroll-at-provision later.
-- [ ] **Node detail page** — placed services, telemetry history, agent
-  version + self-upgrade, **drain/cordon**, remove.
-- [ ] **Node housekeeping** — agent `prune` command (docker system
-  prune, bounded) + optional schedule (`setServerAutoCleanup` analog —
-  disk pressure is the #1 small-VPS killer).
-- [ ] **Multi-node scheduling** — wire `scheduling_rules` (table exists):
-  pin/spread/affinity, prefer-lowest-usage; deploy engine routes to
-  `services.node_id` via agent commands (agent already runs containers).
-- [ ] **Build-on-node** — agents currently `docker run` prebuilt images
-  only; extend agent to pull registry images (build stays central) —
-  private registry creds flow through Phase C.
+- [x] **SSH bootstrap install** — `containr nodes add <user@host>` mints an
+  enroll token, SSHes once (agent/key/default keys), runs
+  `GET /api/agents/install.sh | bash` remotely, closes the session.
+  `--print` emits the one-liner for manual runs; the Usage page shows the
+  same command. Agent binaries ship in the image under `/agents` and are
+  served at `/api/agents/download/{linux-amd64,linux-arm64}` (install
+  script falls back to GH releases). `cli/commands/nodes_add.go`,
+  `api/assets/install-agent.sh`, `agents.go:ServeInstallScript`/`ServeAgentBinary`.
+- [x] **Mesh awareness** — agent reports tailscale/netbird/wireguard/
+  zerotier interface IPs at register (`mesh` field, authoritative on
+  re-register), stored in `node_agents.metadata.mesh`, shown on the node
+  detail page. `TAILSCALE_AUTH_KEY` enroll-at-provision still open.
+- [x] **Node detail page** — `/nodes/:id` (admin): heartbeat telemetry
+  (cpu/mem sparklines over 1h/24h/7d via `GET /agents/:id/metrics`),
+  containers, command history, rename, auto-prune toggle, prune-now,
+  remove. Drain/cordon and self-upgrade deferred — they need
+  `services.node_id` routing which lands with multi-node scheduling.
+- [x] **Node housekeeping** — agent `prune` + `system_df` commands
+  (`docker system prune -af`, volumes excluded unless requested, optional
+  `--until`). `node_agents.auto_prune` + the health sweep enqueue a prune
+  at most once per 24h per node. Surfaces: `POST /agents/:id/prune`,
+  `nodes update --auto-prune` / `nodes prune [--volumes --until]` /
+  `nodes commands`, MCP `containr_nodes_update|prune|commands`
+  (confirm-gated), Usage-page per-node Prune button + auto toggle.
+  `cmd/agent/main.go`, `notification_producers.go:scheduleAutoPrune`.
+- [🟡] **Multi-node scheduling** — phase 1 shipped: `services.node_id`
+  pin (explicit / `auto` = least-loaded online / `local` = clear),
+  `NodeRunner` seam in the deploy engine routes reconcile to the agent's
+  command queue (`create_container` with image/env/cmd/ports/volumes/
+  labels/limits), `container_instances` inventory per (agent, service,
+  replica), remote stop/start/restart/delete fan-out, `GET
+  /nodes/options`, `--node` on services create/update + MCP + OpenAPI +
+  service-detail Placement section. Drain/cordon shipped:
+  `node_agents.schedulable`, `POST /agents/:id/cordon|uncordon|drain`
+  (drain evicts remote containers via the agent queue + unpins services
+  so they redeploy locally), `nodes cordon|uncordon|drain` CLI +
+  MCP (drain confirm-gated) + node-detail page controls; `auto` and
+  explicit pins skip cordoned nodes. Spread placement shipped:
+  `services.spread` distributes replicas deterministically across every
+  online schedulable agent (replica i → agents[i mod n]), mutually
+  exclusive with a pin; `auto` is now resource-aware — least memory
+  utilisation, then cpu, then container count, with uninstrumented
+  agents sorting last. Lifecycle and `GET /runtime` are
+  inventory-driven, so remote replicas show up and tear down wherever
+  they run. Remote ingress shipped: the agent reports assigned host
+  ports in the `create_container` result, the backend renders a
+  Traefik file-provider config per remote service into
+  `TRAEFIK_DYNAMIC_DIR` (shared volume, `watch=true`) pointing the
+  loadbalancer at each replica's mesh IP + published port; route files
+  are rewritten on every remote reconcile and removed on teardown or
+  local placement. Agents report managed-container states at every
+  heartbeat — exits, OOMs, and crash loops land in inventory between
+  reconciles (tombstones never resurrect). Remote sleep/wake shipped:
+  heartbeats carry per-container net counters, idle remote services
+  lose replicas via agent remove + tombstones, and the route file
+  repoints at `/internal/wake-page/:id` on the backend — first hit
+  retriggers the wake reconcile, which recreates replicas and restores
+  real upstreams. Remote nodes run
+  registry-pulled images only — git builds are the remaining
+  documented ceiling. Tag affinity shipped: `node_agents.tags`
+  (operator-set via `PUT /agents/:id` / `nodes update --tags`) +
+  `services.placement_tags` — `auto` and `spread` only consider
+  online schedulable agents carrying every required tag, tags are
+  re-evaluated each reconcile (a tag change re-spreads replicas),
+  unsatisfiable requirements fail with a clear error, pin + tags
+  and local + tags are rejected, empty array clears. Surfaces:
+  `--placement-tags` on services create/update, `--tags` on
+  `nodes update`, MCP args, OpenAPI, node-detail tag editor +
+  service-detail placement-tags input. Remaining: build-on-node,
+  remote sleep/wake, spread weighting by real capacity.
+- [x] **Agent self-upgrade** — `POST /agents/:id/upgrade` enqueues a
+  `self_upgrade` command carrying platform + sha256 + server version;
+  the agent downloads its replacement from `GET /agents/download/
+  :platform`, verifies the checksum, sanity-checks `--version`,
+  atomically swaps its own executable, reports the result, then
+  re-execs (`syscall.Exec`) — no supervisor needed. Agents now stamp
+  `main.version` via ldflags at image build and report it at
+  register/heartbeat (`node_agents.version` refreshes on re-register;
+  older agents keep their stored value). Surfaces: `nodes upgrade`
+  CLI, `containr_nodes_upgrade` MCP (confirm-gated), node-detail page
+  button (online-gated). Ceilings: linux amd64/arm64 only; agents on
+  other platforms get a `NO_BINARY` 409.
+- [x] **Build-on-node** — private registry pulls + real builds shipped.
+  Git sources materialize via `internal/source` checkout (branch/commit,
+  `GIT_ASKPASS` credential injection, dumb-transport fallback), package
+  through `BuildManager.PackageContext`, ship as agent-token artifacts,
+  and `docker build` on the node (`build_image` command). Remote rollbacks
+  `docker save` → artifact → `load_image` on the node. Verified end-to-end
+  on a live agent (PR #60).
 - [ ] **IaC provisioning (ROADMAP §2.2, unchanged)** — Terraform/
   OpenTofu, `infra_connections`, Proxmox + AWS modules, + Hetzner module
   (dflow's second provider), cloud-init → auto-enroll.
-- [ ] **Global/wildcard domain per node** (`nodes.default_domain`) —
-  auto-domains for services on that node.
+- [x] **Global/wildcard domain per node** (`node_agents.default_domain`) —
+  `PUT /agents/:id {default_domain}`; domainless services placed on the
+  node get `<name>.<default_domain>` (pinned → node's base; spread →
+  union of eligible nodes). `serviceDomainNames` resolves them so
+  routing, wake placeholders, and `public_url` all pick them up.
